Likewise, people ask, how do you describe a chemical reaction?
In a chemical change, the molecules in thereactants interact to form new substances. In a physicalchange, like a state change or dissolving, no newsubstance is formed. Explain that another way to say that noatoms are created or destroyed in a chemical reaction is tosay, “Mass is conserved.”
Keeping this in consideration, what is the definition of reactants in chemistry?
Reactants are substances initially present in achemical reaction that are consumed during the reaction tomake products.
Let's start with the idea of a chemical reaction.Reactions occur when two or more molecules interact and themolecules change. Bonds between atoms are broken and createdto form new molecules. That's it.
